Field Collection Host Entity

About

This module provides the host entity for field collection items by adding every host entity as a computed property on field collection bundle level.
There is a patch that does the same. Until the problem is solved this sandbox fixes this problem.

Use case

When indexing field collection items via Search API module, one might need the host entity. The current implementation of the "host_entity" does not provide the needed information, because field collections can be attached to any fieldable entity type. Therefor one can use the "host_entity{entity_type}" property to access the correct host entity and get get its fields into context.
